The display unit 151 may display information processed in the mobileterminal 100. For example, when the mobile terminal 100 is in a phonecall mode, the display unit 151 may display a User Interface (UI) or aGraphic User Interface (GUI) associated with a call. When the mobileterminal 100 is in a video call mode or image capturing mode, thedisplay unit 151 may display a captured image and/or received image, ora UI or GUI.

The display unit 151 may include at least one of a Liquid CrystalDisplay (LCD), a Thin Film Transistor-LCD (TFT-LCD), an Organic LightEmitting Diode (OLED) display, a flexible display, a three-dimensional(3D) display, or the like.

Some of these displays may be configured to be transparent so thatoutside may be seen therethrough, which may be referred to as atransparent display. A representative example of the transparent displaymay include a Transparent Organic Light Emitting Diode (TOLED), and thelike. The rear surface portion of the display unit 151 may also beimplemented to be optically transparent. Under this configuration, auser can view an object positioned at a rear side of a body through aregion occupied by the display unit 151 of the body.

The display unit 151 may be implemented in two or more in numberaccording to a configured aspect of the mobile terminal 100. Forinstance, a plurality of displays may be arranged on one surfaceintegrally or separately, or may be arranged on different surfaces.

Here, if the display unit 151 and a touch sensitive sensor (referred toas a touch sensor) have a layered structure therebetween, the structuremay be referred to as a touch screen. The display unit 151 may be usedas an input device rather than an output device. The touch sensor may beimplemented as a touch film, a touch sheet, a touch pad, and the like.

The touch sensor may be configured to convert changes of a pressureapplied to a specific part of the display unit 151, or capacitanceoccurring from a specific part of the display unit 151, into electricinput signals. Also, the touch sensor may be configured to sense notonly a touched position and a touched area, but also a touch pressure.

When touch inputs are sensed by the touch sensors, corresponding signalsare transmitted to a touch controller (not shown). The touch controllerprocesses the received signals, and then transmits corresponding data tothe controller 180. Accordingly, the controller 180 may sense whichregion of the display unit 151 has been touched.

Referring to FIG. 1, a proximity sensor 141 may be arranged at an innerregion of the mobile terminal blocked by the touch screen, or near thetouch screen. The proximity sensor 141 indicates a sensor to sensepresence or absence of an object approaching to a surface to be sensed,or an object disposed near a surface to be sensed, by using anelectromagnetic field or infrared rays without a mechanical contact. Theproximity sensor 141 has a longer lifespan and a more enhanced utilitythan a contact sensor.

When thetouch screen is implemented as capacitance type, proximity of a pointerto the touch screen is sensed by changes of an electromagnetic field. Inthis case, the touch screen (touch sensor) may be categorized into aproximity sensor.

Hereinafter, for the sake of brief explanation, a status that thepointer is positioned to be proximate onto the touch screen withoutcontact will be referred to as ‘proximity touch’, whereas a status thatthe pointer substantially comes in contact with the touch screen will bereferred to as ‘contact touch’. For the position corresponding to theproximity touch of the pointer on the touch screen, such positioncorresponds to a position where the pointer faces perpendicular to thetouch screen upon the proximity touch of the pointer.

The proximity sensor 141 senses proximity touch, and proximity touchpatterns (e.g., distance, direction, speed, time, position, movingstatus, etc.). Information relating to the sensed proximity touch andthe sensed proximity touch patterns may be output onto the touch screen.

The audio output module 152 may convert and output as sound audio datareceived from the wireless communication unit 110 or stored in thememory 160 in a call signal reception mode, a call mode, a record mode,a voice recognition mode, a broadcast reception mode, and the like.Also, the audio output module 152 may provide audible outputs related toa particular function performed by the mobile terminal 100 (e.g., a callsignal reception sound, a message reception sound, etc.).

The alarm unit 153 may provide outputs to inform about the occurrence ofan event of the mobile terminal 100. Typical events may include callreception, message reception, key signal inputs, a touch input, etc. Inaddition to audio or video outputs, the alarm unit 153 may provideoutputs in a different manner to inform about the occurrence of anevent. The video signal or the audio signal may be output via thedisplay unit 151 or the audio output module 152. Accordingly, thedisplay unit 151 or the audio output module 152 may be classified aspart of the alarm unit 153.

The haptic module 154 generates various tactile effects which a user canfeel. A representative example of the tactile effects generated by thehaptic module 154 includes vibration. Vibration generated by the hapticmodule 154 may have a controllable intensity, a controllable pattern,and so on. For instance, different vibration may be output in asynthesized manner or in a sequential manner.

The haptic module 154 may generate various tactile effects, includingnot only vibration, but also arrangement of pins vertically moving withrespect to a skin being touched (contacted), air injection force or airsuction force through an injection hole or a suction hole, touch by askin surface, presence or absence of contact with an electrode, effectsby stimulus such as an electrostatic force, reproduction of cold or hotfeeling using a heat absorbing device or a heat emitting device, and thelike.

The haptic module 154 may be configured to transmit tactile effects(signals) through a user's direct contact, or a user's muscular senseusing a finger or a hand. The haptic module 154 may be implemented intwo or more in number according to the configuration of the mobileterminal 100.

The memory 160 may store a program for the processing and control of thecontroller 180. Alternatively, the memory 160 may temporarily storeinput/output data (e.g., phonebook data, messages, still images, videoand the like). Also, the memory 160 may store data relating to variouspatterns of vibrations and audio output upon the touch input on thetouch screen.

Also, the mobile terminal 100may operate a web storage which performs the storage function of thememory 160 on the Internet.

The interface unit 170 may generally be implemented to interface themobile terminal with external devices. The interface unit 170 may allowa data reception from an external device, a power delivery to eachcomponent in the mobile terminal 100, or a data transmission from themobile terminal 100 to an external device. The interface unit 170 mayinclude, for example, wired/wireless headset ports, external chargerports, wired/wireless data ports, memory card ports, ports for couplingdevices having an identification module, audio Input/Output (I/O) ports,video I/O ports, earphone ports, and the like.

Referring to FIG. 4, the mobile terminal includes a window 210 a and adisplay module 210 b which constitute the display unit 210. The window210 a may be coupled to one surface of the front case 201. The window210 a and the display module 210 b may be integrally formed with eachother.

A frame 260, configured to support electric devices, is formed betweenthe front case 201 and the rear case 202. The frame 260, a structure forsupporting inside of the mobile terminal, may be configured to supportat least one of the display module 210 b, the camera module 221, anantenna device, an antenna module having a plurality of antenna devices,the battery 240 and a printed circuit board 250.

The frame 260 may be formed so that one end thereof can be exposed tooutside. Alternatively, the frame 260 may constitute part of a slidingmodule which connects a body and a display to each other in a slide-typemobile terminal rather than a bar-type mobile terminal.

Referring to FIG. 4, the printed circuit board 250 is disposed betweenthe frame 260 and the rear case 202, and the display module 210 b iscoupled to one surface of the frame 260. The printed circuit board 250and the battery 240 may be disposed on another surface of the frame 260.The battery case 203 may be coupled to the rear case 202 so as to coverthe battery 240.

The window 210 a is coupled to one surface of the front case 201. Atouch sensing pattern 210 c for sensing a touch input may be formed onone surface of the window 210 a. The touch sensing pattern 210 c isconfigured to sense a touch input, and is formed of a transmissivematerial. The touch sensing pattern 210 c may be mounted to a frontsurface of the window 210 a, and may be configured to convert a changeof a voltage, etc. occurring from a specific part of the window 210 a,into an electric input signal.

The display module 210 b is mounted to a rear surface of the window 210a. In this embodiment, the display module 210 b is implemented as a thinfilm transistor-liquid crystal display (TFT LCD). However, the presentinvention is not limited to this.

For instance, the display module 210 b may be implemented as a liquidcrystal display (LCD), an organic light-emitting diode (OLED), aflexible display, a 3-dimensional (3D) display, etc.

The printed circuit board 250 may be formed on one surface of the frame260 as aforementioned. However, the printed circuit board 250 may beformed below the display module 210 b. One or more electronic devicesare mounted to a lower surface of the printed circuit board 250.

A battery accommodation portion, recessed to accommodate the battery 240therein, is formed at the frame 260. A contact terminal, connected tothe printed circuit board 250 so that the battery 240 can supply powerto the body, 204 may be formed on one side surface of the batteryaccommodation portion.

The antenna device may be formed at an upper end or a lower end of themobile terminal. The antenna device may be formed in plurality at theends of the mobile terminal. In this case, the respective antennadevices may be configured to transmit and receive (transceive) radiosignals in different frequency bands. Such antenna devices may compriseconductive pattern portions formed on one surface of a carrier. Forinstance, a carrier provided with a conductive member may be mounted topart ‘A’ in FIG. 4. The carrier may be coupled to the part ‘A’ of thecase 201 using a coupling means such as screws. In this case, the screwmay be coupled to a hole 262 of the case 201, by passing through athrough hole of the carrier. A rib 263 of the frame 260 to be explainedlater may define a space where the carrier is mounted.

The frame 260 may be formed of a metallic material so as to have asufficient strength even in a small thickness. The frame 260 formed of ametallic material may operate as a ground. That is, the printed circuitboard 250 or the antenna device may be ground-connected to the frame260, and the frame 260 may operate as a ground of the printed circuitboard 250 or the antenna device. In this case, the frame 260 may extenda ground of the mobile terminal.

The printed circuit board 250 is electrically connected to the antennadevice, and is configured to process radio signals (or radioelectromagnetic waves) transmitted and received by the antenna device.For processing of radio signals, a plurality of transceiving circuitsmay be mounted to the printed circuit board 250.

The transceiving circuits may comprise one or more integrated circuitsand related electric devices. As an example, the transceiving circuitsmay comprise a transmission integrated circuit, a reception integratedcircuit, a switching circuit, an amplifier, etc.

As the plurality of transceiving circuits simultaneously feed conductivemembers formed as conductive pattern portions, a plurality of antennadevices may simultaneously operate. For instance, while one of thetransceiving circuits performs signal transmission, another may performsignal reception. Alternatively, both of the transceiving circuits mayperform signal transmission or signal reception.

A coaxial cable may be formed to connect the printed circuit board 250with each antenna device. For instance, the coaxial cable may beconnected to feeding devices for feeding antenna devices. The feedingdevices may be formed on one surface of a flexible printed circuit board(FPCB) 242 for processing signals input from the user input unit 217.Another surface of the FPCB 242 may be coupled to a signal transmissionunit for transmitting signals of the user input unit 217. In this case,a dome may be formed on another surface of the FPCB 242, and an actuatormay be formed at the signal transmission unit.

An antenna device (ANT1) and an antenna device (ANT2) may be formed atone side and another side of the carrier, respectively. The respectiveantenna devices (ANT1, ANT2) are configured to transmit and receivesignals of different frequency bands.

For instance, the first antenna device (ANT 1) may be configured totransmit and receive DCN 1x type or PCS 1x type signals. On the otherhand, the second antenna device (ANT 2) may be configured to transmitand receive DCN EVDO (Evolution-Data Optimized or Evolution-Data Only)type signals.

If the first antenna device (ANT 1) is configured to transmit andreceive LTE B4 type signals, the second antenna device (ANT 2) may beconfigured to transmit and receive LTE B13 type signals.

If the first antenna device (ANT 1) is configured to transmit andreceive signals corresponding to voice service of the mobile terminal,the second antenna device (ANT 2) may be configured to transmit andreceive signals corresponding to LTE service of the mobile terminal.

The flexible printed circuit board (FPCB) 242 is connected to a lowerregion of the carrier. One end of the FPCB 242 may be connected to theprinted circuit board 250 having a controller. The FPCB 242 may beconnected to the user input unit 217 of the mobile terminal. In thiscase, the FPCB 242 is formed so that a signal generated from the userinput unit 217 can be transmitted to the controller of the printedcircuit board 250. For instance, the FPCB 242 may be formed below theuser input unit 217 so as to be connected to the user input unit 217,and so as to contact the signal transmission unit disposed between theuser input unit 217 and the FPCB 242.

FIG. 5 is a conceptual diagram of a mobile terminal according to acomparative embodiment, which illustrates a state where a rear case hasbeen removed from a terminal body. FIG. 6 is a conceptual diagram of amobile terminal according to an embodiment of the present invention,which illustrates a state where a rear case has been removed from aterminal body.

Referring to FIGS. 5 and 6, a processor is mounted to one surface of theprinted circuit board. Such processor may be a micro processor forcommunication or non-communication, which operates at a high speed. Themicro processor may be implemented as a communication chip including acall processor, a modem chip, an RF transceiver chip and an RF receiverchip, and/or a power chip including a power amplifier (PA) chip and apower management IC (PMIC) chip. Alternatively, the micro processor maybe an application processor (AP) configured to drive an OS orapplications and to control various types of system devices orinterfaces in the mobile terminal. Still alternatively, the microprocessor may be an image signal processor (ISP) configured to convertan image signal into an electric signal, a video signal.

Such processor may cause electromagnetic interference (EMI) or radiofrequency interference (RFI) because it is driven at a high speed.Especially, in a case where signal interference occurs from an antennamodule, efficiency or electromagnetic characteristics of an antennadevice may be changed.

Accordingly, as shown in FIG. 5, the antenna module and the processormay be spaced from each other by a distance more than a prescribedvalue, thereby minimizing interference therebetween.

If the battery is disposed at a central region of the terminal body asshown in FIG. 6, the processor and the antenna module are close to eachother. The reason why the battery is disposed at a central region of theterminal body is in order to obtain higher charging efficiency when themobile terminal is wirelessly charged. More specifically, when thebattery is arranged at a position where a wireless power transmissioncoil of a wireless charger overlaps a wireless power reception coil ofthe mobile terminal with facing each other, wireless charging efficiencyis high. However, if the battery is arranged at one side of the terminalbody, coils cannot be effectively arranged. Accordingly, the battery isarranged at a central region of the terminal body, so that the wirelesscharging reception coil can be designed more effectively.

Further, the weight of the terminal body is mainly determined by theweight of the battery. If the battery is arranged at one-sided position,the center of gravity of the terminal body cannot be at a desiredposition. Accordingly, for an effective design of the center of gravity,the battery may be arranged at a central region of the terminal body.

In order to satisfy such design conditions, the battery of the mobileterminal according to the present invention may be arranged at a centralregion of the terminal body.

In this case, the printed circuit board may be formed to cover thebattery. And the processor may be mounted to the printed circuit boardpositioned at an upper region or a lower region of the battery. Theprocessor, formed near the antenna module as shown in FIG. 6, operatesat a high speed, which may badly influence on the operation of anantenna device.

Referring to FIGS. 4 and 6 back, antenna modules may be mounted to anupper part and a lower part of the terminal body, respectively. A firstantenna module 205 mounted at a lower part of the terminal body is amain antenna, which may be configured to provide voice service or LTEservice of the mobile terminal. A second antenna module 206 mounted atan upper part of the terminal body may be configured to provide mobilecommunication service not provided from the first antenna module 205,e.g., GPS, Bluetooth, WIFI, etc. That is, communication service, whichrequires wireless signals of high efficiency or high quality, may beformed at an antenna of the first antenna module 205.

FIG. 7 is a perspective view illustrating a state where a printedcircuit board and an antenna module have been removed from the terminalbody of FIG. 6. FIG. 8 is a perspective view illustrating a state wherethe printed circuit board and the antenna module have been coupled tothe terminal body of FIG. 7.

Referring to FIGS. 4 and 7, the frame 260, configured to support insideof the mobile terminal, may be coupled to the case. The window 210 a maybe coupled to the case. The case may be the front case 201.

The display module 210 b may be coupled to a front surface of the frame260, and may be supported by the frame 260. As shown in FIG. 8, a rearsurface of the frame 260 may be supported by the frame 260, in a statewhere the battery 240, the printed circuit board 250, the first antennamodule 205, the second antenna module 206, etc. have been mountedthereto.

The rear surface of the frame 260 may be divided into a region (A3) formounting the battery 240, a region (A2) for mounting the printed circuitboard 250, and a region (A1) for mounting the antenna module. Apartition wall 263 may be formed so that the region (A1) for mountingthe antenna module can be partitioned from the region (A2) for mountingthe printed circuit board 250.

In case of coupling the printed circuit board 250 where processors 251,252, 253, 254 and 255 have been mounted to the frame 260, an antennadevice may be electromagnetically interfered by the operation of theprocessors 251, 252, 253, 254 and 255. In order to prevent such problem,a shielding member 270 is coupled to the partition wall 263. Theshielding member 270 may be detachably coupled to the partition wall270.

A shielding sheet 266 may be formed at a region where the printedcircuit board 250 is to be mounted. That is, the shielding sheet 266 maybe disposed between the printed circuit board 250 and the terminal body(more specifically, the frame 260), thereby reducing electromagneticinterference of the antenna device due to the operation of theprocessors. Further, the shielding sheet 266 may reduce electromagneticinterference of the processors due to the operation of the antennadevice.

FIGS. 9A and 9B are conceptual diagrams illustrating the printed circuitboard 250 and the shielding member 270 according to an embodiment of thepresent invention, respectively. FIG. 10 is a sectional view taken alongline ‘IV-IV’ in FIG. 8.

Generally, the printed circuit board of the mobile terminal includes amounted electronic circuit. The mounted electronic circuit is sensitiveto electromagnetic interference (EMI) and radio frequency interference(RFI). Especially, the radio frequency interference (RFI) is generatedfrom an interference source inside the mobile terminal, or an externalinterference source. In order to prevent such interference and protectelectric devices, a shielding structure is required. As such shieldingstructures, a shielding member according to an embodiment of the presentinvention may be considered. The shielding member may be formed ofstainless or titanium requiring no plating, and may be formed by moldingin each step using a pressing method.

The printed circuit board includes a conductive layer, and a solderresist layer 259 formed on the conductive layer. The solder resist layer259 is recessed from one surface of the printed circuit board so thatthe conductive layer formed therebelow can be exposed to outside.Protrusions 272 of the shielding member 270, which will be explainedlater, come in electrical-contact with a solder resist open (hereinafterwill be referred to as ‘conductive pattern portion’).

The plurality of processors 251, 252, 253, 254 and 255 are mounted tothe printed circuit board 250. Referring to FIGS. 4, 6 and 9A, the AP251 and the CP 253 may be mounted on the printed circuit board 250disposed between the battery 240 and the first antenna module. In thiscase, PMIC chips 252 and 254 may be connected to the AP 251 and the CP253, respectively so as to manage power supplied to the AP 251 and theCP 253.

The ISP 255 may be mounted on the printed circuit board 250 disposedbetween the battery 240 and the second antenna module.

Reinforcing members 256 and 257, configured to reinforce intensity ofthe printed circuit board 250, may be formed at the printed circuitboard 250. The reinforcing members 256 and 257 may be formed at part ofthe printed circuit board 250 having a relatively smaller thickness,thereby enhancing the entire intensity of the printed circuit board 250.

Referring to FIGS. 9B and 10, the shielding member 270 may include abase portion 271 and protrusions 272. The base portion 271 may becoupled to the partition wall 263 in a covering manner, thereby forminga shielding wall between the antenna module and the processor.

For resistance to a bending characteristic, the base portion 271 mayhave a section bent so that its upper region is narrow but its lowerregion is wide, or so that its upper region is wide but its lower regionis narrow. As shown in FIG. 10, the base portion 271 may include a firstmember 271 a formed to contact an upper surface of the partition wall263, and a second member 271 b or a third member 271 c formed to beinserted into groove portions 263 a formed on two side surfaces of thepartition wall 263. The second member 271 b or the third member 271 c,coupled to two side surfaces of the partition wall 263, may be formed tobe elastically-transformable with respect to the first member 271 a.

The protrusion 272 may be formed in one or more in number. Theprotrusions 272 are formed on an upper surface of the base portion 271,so as to contact the conductive pattern portions 258 of the printedcircuit board 250. The protrusions 272 are bent from an upper surface ofthe base portion 271, toward an upper side. The protrusions 272 areformed to have a prescribed inclination angle (a) from a bending line.The protrusions 272 may be formed to have an elastic force more than aprescribed value, thereby attenuating an impact applied to an electricdevice and maintaining an excellent contact with the printed circuitboard. That is, the protrusions 272 may be formed of an elastic membersuch that its inclination angle is variable according to a pressurizeddegree.

Generally, a right side surface or a left side surface of the conductivepattern portion 258 of the printed circuit board 250 has a width ofabout 1.2 mm. Accordingly, a central region of the conductive patternportion 258 should be disposed within a range spaced from the sidesurfaces by 0.3 mm-0.45 mm. The protrusions 272 should be arranged tocontact the central region of the conductive pattern portions 258.

Especially, if the conductive pattern portions 258 of the printedcircuit board 250 are coupled to the protrusions 272 at the centralregion thereof, electromagnetic interference (EMI) and radio frequencyinterference (RFI) of the mobile terminal are reduced. Further,inferiority of the mobile terminal due to an assembly tolerance, whichoccurs when assembling the protrusions 272 and the conductive patternportions 258, can be prevented. Besides, a ground of the printed circuitboard 250 can be extended, and electromagnetic waves can be effectivelyshielded. That is, in order to enhance a shielding function by theshielding member, eccentricity of the protrusions 272 should beprevented so that the protrusions 272 and the conductive patternportions 258 can be coupled to each other at the central region of theconductive pattern portions 258, not at the edge regions. In order toprevent eccentricity of the protrusions, the width of the conductivepattern portion (SR Open) can be increased. However, in this case, thesize of the printed circuit board should be increased. This may cause alimitation in reducing the size of the mobile terminal.

One end of the protrusions 272 may be formed sharply so as towell-contact the conductive pattern portions 258, or formed to be roundby having the edge removed.

The shielding sheet 266 and the shielding member 270 are formed to coverat least part of various types of electric devices of the printedcircuit board 250, when the frame 260 and the printed circuit board 250are coupled to each other. Under such configuration, a specificabsorption rate (SAR) of the mobile terminal can be enhanced.

FIGS. 11 and 12 are sectional views taken along line V-V′ in FIG. 8,respectively.

Hereinafter, the first module 205, formed at a lower region of the bodyof the mobile terminal and including a main antenna, will be explainedas an antenna module.

The antenna module 205 may be formed to include one or more antennadevices (ANT1, ANT2). That is, two or more radiators of antenna devicesmay be formed at one antenna module 205.

For instance, if the single antenna module 205 includes two antennadevices, radiators of the two antenna devices may be implemented in theform of conductive patterns 205 b printed on an outer surface or aninner surface of a carrier 205 a. If the radiator of the first antennadevice is formed at the left side of the carrier 205 a, the radiator ofthe second antenna device may be formed at the right side of the carrier205 a. In such antenna devices, a point where a maximum current flows,i.e., wireless signals are radiated to the maximum, may be formed at oneend of each radiator.

Referring to FIGS. 11 and 12, the shielding member 270 according to thepresent invention may be positioned on a virtual line which connects apoint (P) of each antenna device where a maximum current flows, to theprocessors. Under such configuration, radiation of wireless signals,occurring from a maximum radiation point of the antenna devices towardthe processors, can be prevented.

Owing to the shielding member 270, not only electromagnetic interferenceof an antenna device due to the operation of the processors can bereduced, but also electromagnetic interference of the processors due tothe operation of the antenna device can be reduced.

In a case where the antenna device is formed in plurality, the shieldingmember 270 may be also formed in plural, so as to effectively shieldsignals radiated from the respective antenna devices. Each of theshielding members 270 may shield a wireless signal radiated toward oneprocessor, from a maximum radiation point of the antenna devices.

One of the shielding members 270 may shield a wireless signal radiatedtoward the AP 251 from one antenna, or a wireless signal radiated towardone antenna from the AP 251. Another shielding member 270 may shield awireless signal radiated toward the CP 253 from another antenna, or awireless signal toward another antenna from the CP 253.

The mobile terminal according to at least one of embodiments of thepresent invention can have the following advantages.

Firstly, electromagnetic interference of the antenna device due to theoperation of the processors can be reduced. Further, electromagneticinterference of the processors due to the operation of the antennadevice can be reduced.
